The leveling knobs located above the mounting feet are secured usingallen head set screws. These set screws must be loosened before the knobs can be moved. The set screws are accessible from the sides of the base. Re-tighten the set screws after leveling the gauge to help ensure that the level adjustment will not shift due to loose screws.

The gauge may be installed with the outer cover on or with it removed. Three screws hold the outer cover in place. Take out these three screws to remove the cover. Carefully remove the cover, avoiding hitting any of the internal rain gauge parts. Some of the moving parts are tied down to prevent movement and possible damage during shipping. Remove any tape, plastic ties, foam inserts, or other objects used to keep the tipping buckets from moving. The bucket assembly should move easily with the packing materials removed.

Chapter 3: Operation

The rain gauge operation is relatively simpleAs. rain is collected by the eight-inch diameter orifice, the rain drops are directed down through the funnel and into the bucket assembly. As soon as the bucket has collected enough rain to represent 0.01 inches (or 0.25 mm) of rain, the bucket tips. The rain drains out through the drain collection tubes and the magnet is moved past the reed switch. The reed switch closes momentarily, making an electrical contact that is used in conjunction with electronic counting and recording instruments.

Chapter 4: Calibration

4.1 Factory Calibration

Each rain gauge is thoroughly tested before being shipped to the customer. A measured amount of water is passed through the rain gauge to give an expected number of counts according to the diameter of the orifice. The bucket calibration posts have screws that are adjusted until the correct number of counts are achieved with repeated testing. The exact number of counts or nearly the exact number are recorded for each gauge. As long as the number of counts is within the specified accuracy of the gauge, the calibration will be accepted. The calibration of the gauge should not change during shipping unless the gauge becomes damaged. Checking of the gauge calibration may be made after the gauge has been installed to ensure the accuracy of the data.

4.2 Calibration Procedure

The rain gauge calibration may be checked using a graduated burette or cylinder. Wet the gauge thoroughly allowing water to flow through the gauge before beginning the test. The

wetting of the gauge helps compensate for water that may adhereportionsto .ofthe gauge causing some error in the counts.
